Abstract
Data delivery in GSM and UMTS co-existing networks is controlled by apparatus located within the network infrastructure which predicts the trajectory of a moving mobile station ( ) requesting transmission or reception of data. By knowing the trajectory of the mobile station ( ), the transmission can be made in an optimum manner by setting an appropriate transmission rate or delaying transmission until the mobile station ( ) reaches a cell ( ) able to accommodate faster data rates than its neighbours ( ). The trajectory prediction is based on a learning process whereby a large population of mobile stations' behaviour in a designated zone ( ) is monitored over a period of time. Mobile stations with like behaviourial characteristics are grouped together. A mobile station ( ) requesting a service for data transmission is matched to one of the recorded groups from which its trajectory can be predicted. The invention has been shown to be able to cut down the transmission times and improve the call drop rate.
